Cheerios commercials featuring a stick figure playing some sport, getting tired, eating cheerios and bouncing back to win. When he'd eat his cheerios you'd hear "Cheeri-iri-os"

My brother and I used to go into the back yard after Saturday morning cartoons when they'd play that commercial and try eating cheerios to make us run faster, we even tried shouting Cheeri-iri-os to see if that helped. It didn't.
